"Toby Keith and Kristen Bell are a terrific one-two knockout punch for the 2012 CMT Music Awards," John Hamlin, SVP, Music Events and Talent, CMT, tells Us Weekly in a statement. "Toby has been involved with our show every year since its inception and Kristen is as entertaining and witty as any young actor working today. We're thrilled to have them both as hosts for this year's show."

Keith -- who is also Billboard's No. 1 Artist of the Decade and No. 1 Country Songwriter of the Decade -- has sold more than 36 million albums worldwide. Bell next appears in the movie Hit & Run, opposite her fiance, Dax Shepard, 37.
